Ada Lovelace Day (ALD) is an international celebration day of the achievements of women in science, technology, engineering and maths (STEM). It aims to increase the profile of women in STEM and, in doing so, create new role models who will encourage more girls into STEM careers and support women already working in STEM.
Founded in 2009 by Suw Charman-Anderson, it is now held every year on the second Tuesday of October. It features a flagship Ada Lovelace Day Live! ‘science cabaret’ event in London, UK, at which women in STEM give short talks about their work or about other women who have inspired them, or perform short comedy or musical interludes with a STEM focus.
